[Q] Can the brightness be lowered even further? (CM7) - AT&T Samsung Galaxy S II SGH-I777

Hey,
I'm running on CM7. Can the brightness on the phone be set lower than the slider-bar allows? I'm often inside dark rooms and would prefer the brightness to be at a lower level. I know the phone can be less bright, because when you turn Desk Clock mode on (from within the Clock App) it set the screen to a super-low brightness. I was wondering if I can have that brightness for normal use.
Thanks.

settings > cm settings > display > automatic backlight > use custom / edit other levels
not sure what settings would accomplish this, or if it is even possible - but those are the settings you are looking for.

I have -no- idea what the settings do, or how to enable it at all. I tried setting everything to the lowest it goes to (2) but it did nothing... Hmm.

Look for "screen filter" app in the market.

Won't this just set a "filter" on top of the screen, making it darker? It won't really affect the actual backlight, will it? I was hoping to both make the screen darker, and save a bit of battery. Don't know how screen work, just what I think is happening.

According to the description and some users it saves battery on amoled screens...but I haven't tested it...you could be right.

Yeah, I downloaded it, and it didn't do anything at all...

A bump to this. Anyone know of a real way?

I believe the effect in the desk clock is essentially the same as Screen Filter. It just darkens it. Just like Desk Clock on the Captivate, evident because the status bar stays the same brightness but the clock lowers. That's why the CM7 app makes the status bar disappear, so the app can darken itself and you won't notice it's darker because it doesn't affect the system and the status bar would have stayed the same brightness. Screen filter is a wonderful option. I had it to "hold menu button" in CM7 settings.

I don't think AMOLED screens have a backlight, that's why they're LED and not LCD.
I have the same problem: at night, the screen is too bright. Cyanogen has an option to only display one of the 3 primary colors, so you can turn on only the red subpixels. Sure, you are left with a monochrome screen, but it is dim and uses less power.

Brightness Settings

Hey guys,
Wat's te ideal brightness setting for the battery? Mines on about 20-30% but in battery usage it says 58% usage and the phone hardl last a day ...
Any thoughts?
Stats in Battery usage graph and your Brightness level is completely two different things.
I always use Auto.
I think I will try that. I also wonder if noled app is having an effect but I set the brightness on that to 1%.
Ever since 2.3.4 I've had mine on full brightness. The battery on 2.3.4 roms has always been good for me.
Is that stock or custom ROM?
Also anyone find that once the battery saver option kicks in that when it recharges that the settings don't switch back to what they were previously? A bit annoying as I don't want to have to manually change my screen timeout etc everytime.
Also what's the option for adjust screen brightness tickbox about just below the general brightness setting? Don't quite understand that.

You mean background effect?
- Dynamic: bright, vivid colors
- Standard: standard colors.
- Movie: contrast higher, warmer image.

I think the option is: "Auto adjust power" int he Display settings menu. Something about analyzing images or something.
Anyone able to expand upon this please?

since its upgrading to samoled+ even we set the brighness to 0 it is still bright but then again depending your eyes and needs of battery consumption (bc) theres also a"custom rom"way like hollow to follow or if you prefered moderate usage without flashing i think on 20-30% bright it contribute to bc
My browser is set is have the brightness at 0 which is fine, I think there's a service in the background using more CPU than it needs. Likelihood it is a Glu game ~.~.

Color temp changing in browser

Is it normal that my color temperature seems to be changing when I'm in the browser. I notice it the most in there due to the white background. I'm running serendipity 8 but noticed before this. I'm not running the dynamic screen mode. Only the standard. Is this related to the auto brightness? Haven't tried disabling it yet but this color change is quite annoying as it goes from like cool to warm colors.

I'm getting the same on stock rooted. I think it's related to auto-dim because it's at 15 seconds, which is what my auto-dim is set to. Did you time it and verify the same for yours? Not sure why it doesn't just dim like past models, but goes to gross 1970's TV looking color haha
I believe you can adjust browser brightness aside from you regular screen brightness. When you bring up the browser again, look under setting and you will see "browser brightness"...let me know if that helps.

The browser auto brightness toggle is jenky... when set to auto its when it kicks to low brightness the colors go warm yellow. If set to manual just above that point it disables the rest of the OS's auto dimness and the whole android is too bright dohh.
Color Temp of Browser
Is this just in your browser or does it show up on all white backgrounds? I thought my screen was defective because it would change color temperature with the backlight but the real culprit was that setting under Settings | Display which automatically checks the image being displayed and adjusts it to save battery power... I don't have the phone with me right now so I can't give the exact wording of the option, sorry.

Seems most noticeable in the browser because it is the only thing with a white background.
I see this problem mainly using the xda app... I will scroll and as I'm holding down on the screen, it will be sliiiiiightly pinkish... then as soon as I let go and the screen is static, it reverts to a cool blue... very slight

Possible to make the screen even dimmer?

Running ViperRez. Is there a way to make the screen any dimmer than the current lowest setting? . I find it is still too bright at night.

I remember it getting quite dim but you should search for a mod or script.
This should be in the Q&A Section though, not development. Happy searching.

get yourself an app like notification toggle or do it manually in brightness settings. automatic brightness isn't great cause it's always checking light levels every to confirm if brightness needs to be increased or decreased. notification toggle will allow any percentage and as many levels as you want. I use 10,15,20,25,40,50 and 100
youre gonna want to get this app https://play.google.com/store/apps/details?id=com.haxor&feature=nav_result#? t=W251bGwsMSwxLDMsImNvbS5oYXhvciJd. its free and it works perfectly and you can make it as dim as you want, even to the point where you cant see the screen on at all, i used to use it to text at night all the time. It also should save your battery, i could go two plus hours screen on time on wifi and be in the high 70s for battery on my inc 2
Quicker. It has screen dim in it. I use it every night.

This works perfectly! Thanks for the help.
I use screen filter too, but keep in mind that it only draws a dark overlay on your screen to let out less light. The LED back light is still at the same level, but less light escapes. So, it really doesn't help your battery since we don't have AMOLED screens.
Chainfire 3D has a "Night Mode" filter if you want to give that a try too: https://play.google.com/store/apps/details?id=eu.chainfire.cf3d
The free version currently has a red-, green-, or blue-only RGB channel filter, as well as Amber and Salmon colored filters. You can fully adjust the RGB values of the filter in the Pro version.
Oddly, there is no "balanced coloring" grayscale filter. Would need to use the previously mentioned app or buy the Pro version and adjust the RGB values equally.
Fun to try out at any rate.
I use Lux. It allows you to reduce screen brightness to completely black and unreadable. I don't know but I don't think it justs adds a transparent black overlay to make it look darker. It seems to actually adjust the brightness below the minimum allowed without the app. Here's a link to it in the market (there is a paid and free version) https://play.google.com/store/apps/...ps#?t=W251bGwsMSwxLDEwOSwiY29tLnZpdG8ubHV4Il0.

Second Screen dimming

Just got the V10 and the second screen dims after 2 or 3 seconds after turning off the main screen. Is there a way to adjust the timing when the second screen dims? The dimmed second screen is almost unreadable because it is so dim.
Ditto, the idea that this is a replacement for a notification LED is really damaged by the dimming. (It's not just me that bought the phone based on that idea, right?) What I've found so far:
With the screen brightness set to 0, the second screen dims fully a few seconds after sleeping. Icons become about as noticeable as dust reflections.
With the screen brightness set to 100, the second screen follows the ambient light sensor after sleeping. Under bright light it turns itself up to the point where it's useable.
I've been playing with all the LEDs that Light Flow sees, but at least without root, nothing has any effect. I might look through the /sys files later. We probably need to get root first to figure this out.
On auto brightness it seems to be that the device adjusts the dimmed display for the ambient lighting? It's not the easiest thing in the world to see, but it's certainly not hard for me to see what notifications I have. I really prefer this over a colored LED.
Light Flow settings
For what it's worth, here's my current setup, now that the T-Mobile H901 is rooted. This does no one without root any good, and I don't know how it would translate to similar LED managers. I've been using Light Flow since the Sapphire (MyTouch 3G).
Light Flow device settings: check direct mode, root mode, and run every command as root. The Nexus 5 force reset option is checked by default and I don't know if that's relevant (no calls yet). Everything else in the menu is unchecked.
Let Light Flow control lcd-backlight-ex.
In a notification, set that "LED" to Solid and to 255 brightness. Check Enable Mixer and App controlled flash. With that last setting, the app will reset the brightness every few seconds even if the system dimmed it due to an ambient light change.
Now I need to edit some notification icons to be big and colorful. I wonder how this will impact battery life? Now the app is going to be awake all the time.
I've noticed that today on auto brightness the second screen will increase in light but not much. It also is not as smoth of a transition as on main display. It kinda jumps up real quick..
Yes for me I've noticed on Auto brightness the second screen will dim in a dark room and if you turn off your phone while in that room then come out... The second screen is still dim.... It's like th second screen doesn't respond to the light sensors at all unless the main screen is on.

It would have been nice if lg included the capability to change the second screen settings such a brightness or text color.

Another one of many things that it would be cool to see baked into a custom stock rom. Good stuff. I wonder if Cloudyfa might come over and cook on this awhile. I have always loved his stock Roms....

Color would be cool. A classic CRT bright/lime green, for instance, would probably show up much better than the white.
We need to get on their forums with these ideas. Maybe some will get squeezed into an update
An app which turns off auto dim in case screen is off would be pretty much help. Maybe I'll develop one.

The screen is way too bright and there's no way to adjust it when outdoors

So when you're outdoors, even if it's overcast there's no way to slide the brightness down (It auto-snaps to full brightness) even though it's not needed.
I have situations where i could easily use half brightness but my phone forces auto max light
YES, I know i can disable auto brightness completely, but that would not be convenient.
Any fix for this?
I use an app called Lux. Tons of options with it.

Hmmmm, Im not sure how it works but it does have an auto mode which you can tweak on the fly.
I have noticed that also. It also jacks up the contrast to make it easier to see.
It makes pics you took look terrible when viewing them outside. I had to learn to NOT delete them until I check them indoors. I assumed some pics I took were crap at first, but it was just the jacked screen contrast that made them look bad.
On my S9+ in bright sunlight it happens that not only something happens to the contrast and colors (eg. reds become somewhat pinkish) but also black elements on screen start flickering/smudging while scrolling. It looks like the device turns into some sort of brightness boost mode.
Does anyone else experience anything like that?

That's exactly what happens to me. Also if you slide the screen you can see how it the colors are totally distorted.

Check out the screenshot. There's an option to enable brightness slider in the notification bar. Becomes easier to adjust brightness just by sliding down the notification bar.

Did you read what the problem is? outdoors it snaps to max no matter what. (Unless not in auto mode)
Any solution for this problem?
Turn off auto brightness when outdoors..
Guys I've noticed that even if you turn off auto brightness go out in the sun and turn the screen up to max manually,it will kick up into super brightness mode or shine a led light at the sensor when indoors simulating the sun,just like it does with auto brightness on.sammy really want us to get burn in I think so we have to buy new screens all the time?

Never had a screen burn in on a Samsung phone. Don't worry
Guys, idk if this is a S10 only feature (or Android Pie), but when I'm on that situation, if I lower the brightness slider and leave it there for a second or two, the brightness will actually stay down and not jump back up again. Worth a try.

After the S9+'s update to Pie some of the old settings get copied to the new OS, but if you don't go into the settings and check, things might not be configured correctly - I had to choose a different setting and then choose again what was previously selected to ensure that it was written into the Settings correctly.
With the new update the "Automatic Brightness" applies to the AOD - see here in this screenshot, my search of the Settings for the word "auto brightness", see what comes up in attachment #1.
What you need to do is go to the "Adaptive Brightness" and turn it on, then manually adjust your brightness under a few different conditions (EG: Indoors lights off, outside and overcast, and bright sunny day). Now your phone will understand what setting you want for different conditions and automatically adjust the brightness based on lighting conditions, see attachment #2.
The "auto brightness" is now used for the AOD, and has nothing to do with brightness when unlocked. The reason it "auto snaps to full brightness" is likely because previous settings were just copied over after the update and you haven't setup (and trained) the new "Adaptive Brightness" for various light levels. The AOD has both "Auto Brightness" and double-tap the clock to adjust AOD brightness.
